Docklight and Docklight Scripting support checksum areas for on-the-fly calculation of checksums/CRCs, both for Send Sequences (commands sent) and Receive Sequences (responses received). See the user manual section “Calculating and Validating Checksums” for more details.

In Docklight Scripting you can additionally perform checksum calculations with your script code,
using the “DL.CalcChecksum” method.
